Description
Technical Field
[0001] The utility model relates to the technical field of optical cable strengthening core fixing, in particular to an optical cable strengthening core fixing device. Background Technique
[0002] An optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a coated sheath as a transmission medium and can be used alone or in groups. An optical cable is mainly composed of optical fibers (glass filaments as thin as hair), a plastic protective sleeve and a plastic outer skin. There are no metals such as gold, silver, copper, and aluminum in the optical cable, and generally there is no recycling value. An optical cable is a communication line in which a certain number of optical fibers are formed into a cable core according to a certain method, with a sheath on the outside, and some are also covered with an outer protective layer to realize the transmission of optical signals.
[0003] For the current connection and fixation of the optical cable strengthening core, usually the user uses pliers to twist two optical cables together. This method has high requirements for the user's operation, and it is inconvenient to disassemble when there is a mistake. The optical cable is easy to fall off, and the waterproof performance of an ordinary optical cable junction box is poor, affecting the long-term use of the device. For this reason, we propose an optical cable strengthening core fixing device. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an optical cable strengthening core fixing device. The driving gear makes two driven gears move in opposite directions, so that multiple strengthening cores are wound and twisted together. There is not only a large space for twisting, but also the length of the strengthening core twisting is increased, thereby enhancing the stability of the connection between the two strengthening cores, and effectively solving the problems in the background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: an optical cable strengthening core fixing device, including a joint box and a cover plate;
[0006] A cover plate is arranged above the joint box. Through holes I are opened at both ends of the joint box. Fixed arc plates are symmetrically arranged at both ends inside the joint box. Connecting plates are symmetrically arranged between the fixed arc plates. Driven gears are arranged on the inner sides of the connecting plates.

The rotating plate is rotatably connected to the bottom end of the joint box. The rotating plate is fixedly connected to the driving gear through a connecting rod. A connecting shaft is fixedly connected to the rotating plate.
[0008] When connecting the strength members between two optical cables, first pass the two optical cables through the first through holes on the joint box respectively, then pass the strength members on them through the corresponding round holes on the driven gears respectively, and then rotate the driving gear by adjusting the connecting shaft. The driving gear makes the two driven gears move in opposite directions, so that the strength members are wound and twisted together.

[0009] Furthermore, threaded holes are provided on the rotating plate, and threaded holes are also evenly provided at the bottom end of the joint box. The screws are all threadedly connected to the threaded holes on the rotating plate and the joint box.

[0013] Furthermore, rubber sleeves are provided in the first through holes, and the rubber sleeves are fixedly connected to the inner walls of the first through holes.
[0014] The setting of the rubber sleeves can play a protective role when the optical cable passes through the first through holes on the joint box, and can also play a sealing role.
[0015] Furthermore, sliding grooves are symmetrically provided on one connecting plate. Both ends of the upper pressing plate are slidably connected to the sliding grooves. Card slots are provided on both ends of the upper pressing plate and the inner walls of the sliding grooves. The card slots are all clamped with the clamping blocks. The upper ends of the clamping blocks are fixedly connected to the sliders. The other connecting plate is fixedly connected to the inner side. Slide rails are symmetrically installed at the lower end of the lower pressing plate. The slide rails are slidably connected to the driving gear through the annular grooves.
[0016] After the strength members are twisted, then through the cooperation of the upper pressing plate with the sliding grooves and the card slots, the twisted strength members are fixed between the upper pressing plate and the lower pressing plate for pressing and limiting, so as to prevent the driving gear from moving due to external factors and causing the wound strength members to become loose.
[0017] Further, a sealing groove is provided at the upper end of the joint box. A sealing plate is arranged in the sealing groove and fixedly connected to the lower end of the cover plate. Grooves are symmetrically provided on the outer side of the cover plate. A rotating block is rotatably connected between the support plates.
